Evidence for muon production from neutrino interaction with water; from wiki;
Super Kamiokande is a large volume of water surrounded by photomultiplier tubes that watch for the Cherenkov radiation emitted when an incoming neutrino creates an electron or muon in the water.
If meson production occurs from n reaction with protons in H2O, surely n reaction with UDD/H is highly likely to generate muons too. One could propose UDD/H/Hydrinos/Hydrotons as highly effective n detectors simply due to their Ultra-high density. Problem solved?
